IMPROVEMENT IN CLEVISES.

Specification forming part of Letters Patent No. 118,050, dated August15, 1871.

To all whom it may concern:

Be it known that I, SAMUEL W. POPE, of Louisville, in the county of Jeiferson and State of Kentucky, have invented a new and usefulImprovement in Olevis 5 and I do hereby declare that the following is afull and exact description of the same, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

This invention has for its object the production of a cheap and simpleclevis, by means of which a large number of adjustments of the lines ofdraft may be made; and consists in certain details of construction,which will be fully described hereinafter. A

In the drawing, Figures l and 4 represent plan views of my improvedclevis, and Figs. 2 and 3 side elevations of the sa-me.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe fully its construction and manner of operation.

A represents the front end of a plow-beam. B B represent side plates,constructed of suitable pieces of metal having their rear ends curved,as shown, and provided with orifices b b b, and their front ends bentslightly outward, and provided with the large orifices b. These sideplates are connected to the beam by suitable bolts. O represents atransverse connecting-piece, formed of a suitable metallic rod bent intocorrugated form, as shown, the ends of which lrest in the orifices b.Its length, it will be observed, is greater than the width of spacebetween the ends of the side plates, and consequently one of its endsprojects beyond one of the side plates, as shown. D represents adouble-hooked loop for connecting the draft devices to the clevis. Thehooks of this loop rest, when in place, in the depressions c of theconnecting-piece O. From the peculiar construction of the latter it willbe observed that the hooks of the loop may rest in two positions, eithercentrallybetween the side plates, as shown in Fig. 4, or with one hookupon each side of the side plate adjacent to the projecting end of theconnecting-piece C, as shown in Fig. l. By this means a central draftmay be obtained, or a side draft. By turning the connecting-iron over,its position in the side plates will be chan ged-that is, it will bemoved the width of one of the depressions to one side, so that if theconnecting was so extended previous to the change as to permit aright-hand draft, if desired, it would be possible to obtain a left-handdraft after the change. By using a single hook intermediate changes maybe made.

By the construction shown seven lateral adjustments of the draft may bemade, three adjustments being possible with the double hook, and fourwith'the single hook.

The vertical adjustments of the clevis are made by causing the sideplates to swing up or down upon the center bolt, they being secured inthe desired position by means of the rear bolt, which passes through theorifices b, as shown. If further vertical adjustment is desired it canbe obtained by taking off the side plates and by placing them invertedupon the opposite sides of the beam, as shown in Fig. 3. If desired,also, vertical adjustment can be obtained by hooking the loop over orunder the connecting-rod.

The device described is exceedingly simple in its construction, andrenders it possible to obtain a large number of adjustments of the linesof draft.- If desired, also, a one-horse clevis may be made with a lessnumber of corrugations, as indicated at x.

Having thus fully described my invention, what I claim, and desire to.secure by Letters Patent, is-

The clevis-rod O, bent substantially as described, in combination withthe side plates B, or their equivalents, as set forth.

This specification signed and witnessed this 27th day of May, 1871.

SAMUEL W. POPE.
